ZEPTOOLS - The Effect of Charge Effect in Scanning Electron Microscopy (SEM) Observation and Its Elimination

Scanning electron microscopy (SEM) is a powerful observation tool widely used in materials science, biology and other fields. However, the charge effect is a common and unpleasant phenomenon during SEM observation and can negatively affect image quality. In this article, we will introduce the formation principle of the charge effect, its effect on the image, and the effective methods to eliminate the charge effect.

Reduction and correction of sample surface charging effects in scanning electron microscopy imaging

Scanning electron microscopy (SEM) is a powerful imaging technique capable of providing high-resolution images of the sample surface. However, the charging effect on the sample surface often leads to image distortion and noise, which affects the imaging quality of the SEM. In this article, we will describe some common methods to reduce or correct the surface charging effect of the sample, thereby improving the accuracy and reliability of SEM imaging.
